BACKGROUND Field of the Invention

The present invention is directed to intelligent door lock systems, and more particularly to intelligent door lock systems, mobile devices and accelerometers.

Description of the Related Art

Door lock assemblies often include deadbolts. Typically such an assembly included a latch which is depressed during closure of the door and, with substantially complete closure, extends into a recess of the door strike. Such a latch by itself is often easy to improperly depress-release by an unauthorized person, with a card-type element or even a pry bar. Also the outer knob assembly can be torqued off with a wrench to gain access to the mechanism and thereby to the room closed by the door. Deadbolts are not as susceptible to these unauthorized activities. Doors having deadbolts typically use a latch mechanism. This is because (1) the latch holds the door snug against rattling whereas the deadbolt by necessity must have clearance between it and the strike plate recess edges (but because of the clearance, the door can rattle), and (2) the latch automatically holds the door shut since it is only momentarily depressed during door closure from its normally extended condition and then extends into a door strike recess when the door is fully closed.

Except in rare devices where the deadbolt is operated by an electrical solenoid, the deadbolt, to be effective, must be manually thrown by a person inside the room or building, or if the deadbolt is actuatable by an external key, the person leaving the room or building must purposely engage the deadbolt by a key as the person leaves. However, if a person forgets to so actuate the deadbolt, either manually with an inner hand turn when inside, or by a key outside, an intruder need only inactivate the latch mechanism in order to gain unauthorized entry. Motel and hotel rooms often do not even have a key actuated deadbolt and thus are particularly susceptible to unauthorized entry and theft when the person is not in the room.

In recent years, mechanisms were developed to enable retraction. i.e. inactivation, of the deadbolt simultaneously with the latch for quick release even under panic exit conditions. But to lock the door still required manual actuation of the deadbolt with the inner hand turn or a key on the outside.

In one door lock assembly a deadbolt is shift able between an extended lock position and a retracted position and means for shifting the deadbolt from the extended position to the retracted position which is characterized by biasing means for applying a bias on the deadbolt toward the extended lock position; restraining means for restraining the deadbolt in the retracted position against the bias of the biasing means and being actuatable to release the deadbolt to enable the biasing means to shift the deadbolt to the extended lock position; and trigger means. For actuating the restraining means to release the deadbolt and thereby allow the biasing means to shift the deadbolt to the extended lock position.

Such a door lock assembly is for use in a door frame and thus the invention extends to the door lock assembly of the present invention in cooperation with a door frame.

Some deadbolt locks are automatically actuated with closure of the door, the deadbolt being mechanically actuated to the extended lock position. The deadbolt in its retracted position is spring-biased toward the extended lock position, but is retained in a cocked condition by a deadbolt restraining and releasing device which is trigger actuatable to activate the deadbolt into its locked condition. The trigger mechanism may have a portion that protrudes from the door to engage the door strike of the door frame upon closure of the door, thereby causing the deadbolt to be released and shifted to the locked condition. The protruding portion of the trigger mechanism can also serve to hold the door snug against rattling.

In another door lock assembly for a hinged door and cooperative with a door strike of a door frame, a deadbolt is provided mounting in the door. The dead bolt is shift able between a retracted non-lock position and an extended lock position. It includes a manually operable device for shifting the deadbolt from the extended lock position to the retracted non-lock position. A biasing device applies a bias on the deadbolt toward the extended lock position. A restraining device is biased into a restraining relationship with the deadbolt in the retracted position. This restrains the deadbolt in the retracted position against the bias of the biasing device. A trigger releases a restraining means when the trigger is actuated and includes a protruding portion for engaging a door strike for actuating the trigger. A door strike includes a surface to engage and depress the trigger protruding portion for actuation of the trigger and release of the deadbolt restraining means, and includes an opening to receive the deadbolt when extended.

The use of electronic systems for the control and operation of locks is becoming increasingly common. The present invention is directed to an arrangement that permits the electronic and manual control of the lock operation to be separated to allow manual operation of the lock independently of the electronic drive system for the lock. The lock of the present invention is useful in situations where an electronic controller is temporarily unavailable, for example where a controller has been lost, misplaced or damaged.

There are currently some electronic deadbolt lock arrangements. In one device, a lock has a bolt movable between locked and unlocked conditions. The lock has a manual control device that serves to operate the lock between locked and unlocked conditions. A power drive is coupled by a transmission to the manual control device. The lock is operated between the locked and unlocked conditions in response to operation of the power drive. A transmission mechanism couples the manual control device and the power drive, whereby the lock moves between the locked and unlocked conditions. The transmission mechanism is operable to decouple the power drive from the manual control means to enable the lock to be operated by the manual control device independently of the power drive.

However, most deadbolts require that a user manually use a metal key to lock or unlock the deadbolt. There is a need to provide a deadbolt that can be retrofitted to an existing door. There is further need for a deadbolt that can be locked or unlocked electronically, automatically, and remotely. There is a need for an intelligent door lock system where a position of a drive shaft, coupled to a dead bold, is used to detect if the dead bold, lock, is locked, unlocked, a depth of the dead bold travel and the like. There is a further need for an intelligent door lock system where the drive shaft is repositioned in an absolute state. There is a further need for an intelligent door lock system where the a positioning sensing device is positioned on a drive shaft, or an element coupled to the drive shaft, and a rotation of the drive shaft, along a Z axis, provides information relative as to whether someone has used a key, the ring, lock picking and the like.

In one embodiment the bridge 11 provides communication to other Bluetooth devices 21 without the use of a mobile device. As non-limiting examples, the bridge 11 allows: WiFi-enabled devices in a dwelling to interact with Bluetooth devices 21 in the dwelling; WiFi-enabled devices in a dwelling to interact with the intelligent door lock system 10 over Bluetooth; allows a Bluetooth device 21 in a dwelling to interact with Internet-based services and API's using a dwelling's home WiFi network and Network System connection; allows people to operate an intelligent door lock system and other Bluetooth devices over a Network System from anywhere outside a dwelling; extend network coverage of Bluetooth devices in a dwelling in order to understand who is in the dwelling, who is away, who is coming and who is going when doors 12 and lock devices 22 are operated and the like.

In one embodiment the bridge 11 extends Network System coverage of Bluetooth devices 21 other than lock devices 22 to perform device-specific operations, including but not limited to: gathering information about the presence of the Bluetooth device 21, the operational status of the Bluetooth device 21, the operational history of the Bluetooth device 21 and performing Bluetooth device 21 specific operations including but not limited to: turning the Bluetooth device 21 off and on, changing the mode of operations of the Bluetooth device 21, changing the operational settings of the Bluetooth device 21 and scheduling these device operations based on ad hoc, daily, weekly, monthly or other schedules.

In one embodiment the intelligent door lock system 10 trusts the bridge 11 for commands (remote status) after an intelligent door lock system owner or designee is registered at the back-end of the intelligent door lock system using a cloud lock access services-based access system that grants the bridge 11 access to the intelligent door lock system 10.

In one embodiment the intelligent door lock system 10 owners or designee rants the bridge 11 access to the lock device 22 by using their digital credentials, which can be stored at the cloud lock access services or at the back-end 68, to pair a specific bridge 11 with a specific intelligent door lock system 10 grant specific rights. As non-limiting example, the specific rights include but are not limited to, gathering of status and operational history of the system 10, triggering lock device 22 operations in real-time, as well as applications for interfacing with the bridge 11 and a Bluetooth device 21.

In one embodiment the door lock system 10 includes a vibration/tapping sensing device 11 configured to be coupled intelligent lock system 10. In one embodiment the intelligent door lock system is in communication with a mobile device that includes a vibration/taping sensing device to lock or unlock a door associated with the intelligent door lock system.

In one embodiment the vibration/tapping sensing device 11 senses knocking on the door and locks or unlocks the door. In one embodiment the vibration/tapping sensing device 11 is not included as part of the actual intelligent door lock system. In one embodiment the vibration/tapping sensing device 11 is coupled to the drive shaft 14. It will be appreciated that the vibration/tapping sensing device 11 can be coupled to other elements of the intelligent door lock system 10. The vibration/tapping sensing device detects vibration or knocking applied to a door that is used to unlock or lock the intelligent door lock system 10. This occurs following programming the intelligent door lock system 10. The programming includes a user's vibration code/pattern, and the like. Additionally, a user can give a third person a knock code/pattern to unlock the intelligent door lock system of the door. The knocking is one that is recognized as having been defined by a user of the door lock system as a means to unlock the door. The knocking can have a variety of different patterns, tempos, duration, intensity and the like.

The vibration/tapping sensing device 11 detects oscillatory motion resulting from the application of oscillatory or varying forces to a structure. Oscillatory motion reverses direction. The oscillation may be continuous during some time period of interest or it may be intermittent. It may be periodic or nonperiodic, i.e., it may or may not exhibit a regular period of repetition. The nature of the oscillation depends on the nature of the force driving it and on the structure being driven.

Motion is a vector quantity, exhibiting a direction as well as a magnitude. The direction of vibration is usually described in terms of some arbitrary coordinate system (typically Cartesian or orthogonal) whose directions are called axes. The origin for the orthogonal coordinate system of axes is arbitrarily defined at some convenient location.

In one embodiment, the vibratory responses of structures can be modeled as single-degree-of-freedom spring mass systems, and many vibration sensors use a spring mass system as the mechanical part of their transduction mechanism.

In one embodiment the vibration/tapping sensing device 11 can measure displacement, velocity, acceleration, and the like.

Suitable potentiometers are disclosed in, U.S. Pat. No. 2,680,177, EP1404021A3, CA2676196A1, incorporated herein by reference.

In various embodiments, the positioning sensing device 16 is coupled to the drive shaft 14 by a variety of means, including but not limited to the adapters 28. In one embodiment, the position sensing device 16 uses a single measurement, as defined herein, of drive shaft 14 position sensing which is used to determine movement in order the determine the location of the drive shaft 14 and the positioning sensing device 16.

The exact position of the drive shaft 14 can be measured with another measurement without knowledge of any previous state. Single movement, which is one determination of position sensing, is the knowledge of whether the door 12 is locked, unlocked or in between. One advantage of the accelerometer 16 is one can determine position, leave if off, come back at a later time, and the accelerometer 16 will know its current position even if it has been moved since it has been turned off. It will always know its current position.

In one embodiment the position sensing device 16, including but not limited to the accelerometer 16, provides an acceleration signal to a controller coupled to the intelligent door lock system 10 and included as part of the intelligent door lock system, or positioned at the door 12, in response to sensed acceleration.

In one embodiment the positioning sensing device 16, including but not limited to the accelerometer 16, provides an acceleration signal to a controller, at the intelligent door lock system 10, in response to sensed acceleration.

In one embodiment the intelligent door lock system 10 includes an accelerometer 16 for determining movement, such as a knock or the door opening, in which the lock is disposed and controlling a radio or the intelligent door lock system 10 via a controller, as a function of the acceleration signal.

In one embodiment, the mobile device 201 includes an accelerometer 1246 and outputs an acceleration signal to a controller 1218 upon acceleration of the mobile device 201. The acceleration signal is output to the controller 1218 and a radio signal generator is triggered to begin generating a radio signal.

In one embodiment a wireless access control system for a door includes a lock assembly 10 coupled at the door 10 and has a lock, wireless circuitry and a controller that in operation provides for a change in the lock for a locked and lock position, and further can have a proximity detector. A user mobile device 201 is in communication with the lock assembly 10. An accelerometer 16 can be at the door, the lock system 10 and/or the mobile device 201.

In one embodiment, the positioning sensing device 16 is directly coupled to the drive shaft 14, as illustrated in FIG. 1(d). Sensing position of the positioning sensing device 16 is tied to the movement of the drive shaft 14. In one embodiment with an accelerometer 16, the accelerometer 16 can detect X, Y and Z movements. Additional information is then obtained from the X, Y, and Z movements. In the X and Y axis, the position of the drive shaft 14 is determined; this is true even if the drive shaft 14 is in motion. The Z axis is used to detect a variety of things, including but not limited to, door 12 knocking, picking of the lock, break-in and unauthorized entry, door 12 open and closing motion. If a mobile device 201 is used to open or close, the processor 36 determines the lock state.

In one embodiment, the same positioning sensing device 16 is able to detect knocks by detecting motion of the door 12 in the Z axis. As a non-limiting example, position sensing is in the range of counter and clock wise rotation of up to 180 degrees for readings. The maximum rotation limit is limited by the position sensing device 16, and more particularly to the accelerometer cable. In one embodiment, the result is sub 1° resolution in position sensing. This provides a higher lifetime because sampling can be done at a slower rate, due to knowing the position after the position sensing device 16 has been turned off for a time period of no great 100 milli seconds. With the present invention, accuracy can be enhanced taking repeated measurements. With the present invention, the positioning sensing device 16, such as the accelerometer, does not need to consume additional power beyond what the knock sensing application already uses.

In one embodiment, the position sensing device 16 is positioned on the drive shaft 14, or on an element coupled to the drive shaft 14. In one embodiment, a position of the drive shaft 14 and power sensing device and/or a torque limited link 38 are known. When the position of the drive shaft 14 is known, it is used to detect if the bolt/lock 24 of a door lock device 22 is in a locked or unlocked position, as well as a depth of bolt/lock 24 travel of lock device 22, and the like. This includes but is not limited to if someone, who turned the bolt/lock 24 of lock device 22 from the inside using the ring 32, used the key to open the door 12, if the door 12 has been kicked down, attempts to pick the bolt/lock 24, bangs on the door 12, knocks on the door 12, opening and closing motions of the door 12 and the like. In various embodiments, the intelligent door lock system 10 can be interrogated via hardware, including but not limited to a key, a mobile device, a computer, key fob, key cards, personal fitness devices, such as Fitbit®, nike fuel, jawbone up, pedometers, smart watches, smart jewelry, car keys, smart glasses, including but not limited to Google Glass. and the like.

During a power up mode, the current position of the drive shaft 14 is known.

Real time position information of the drive shaft 14 is determined and the bolt/lock 24 of lock device 22 travels can be inferred from the position information of the drive shaft 14. The X axis is a direction along a width of the door 12, the Y axis is in a direction along a length of a door 12, and the Z axis is in a direction extending from a surface of the door 12.

In one embodiment, the accelerometer 16 is the knock sensor. Knocking can be sensed, as well as the number of times a door 12 is closed or opened, the physical swing of the door 12, and the motion the door 12 opening and closing. With the present invention, a determination is made as to whether or not someone successfully swung the door 12, if the door 12 was slammed, and the like. Additionally, by coupling the position sensing device 16 on the moveable drive shaft 14, or coupled to it, a variety of information is provided, including but not limited to, if the bolt/lock 24 is stored in the correct orientation, is the door 12 properly mounted and the like.

In one embodiment, a calibration step is performed to determine the amount of drive shaft 14 rotations to fully lock and unlock the bolt/lock 24 of lock device 22. The drive shaft 14 is rotated in a counter-counter direction until it can no longer rotate, and the same is then done in the clock-wise direction. These positions are then stored in the engine memory. Optionally, the force is also stored. A command is then received to rotate the drive shaft 14 to record the amount of rotation. This determines the correct amount of drive shaft 14 rotations to properly lock and unlock the lock device 22.

In another embodiment, the drive shaft 14 is rotated until it does not move anymore. This amount of rotation is then stored in the memory and used for locking and unlocking the lock device 22.

In another embodiment, the drive shaft 14 is rotated until it does not move anymore. However, this may not provide the answer as to full lock and unlock. It can provide information as to partial lock and unlock. Records from the memory are then consulted to see how the drive shaft 14 behaved in the past. At different intervals, the drive shaft 14 is rotated until it does not move anymore. This is then statistically analyzed to determine the amount of drive shaft 14 rotation for full locking and unlocking. This is then stored in the memory.

The intelligent door lock system 10 can be a new lock system mounted to a door 12, with all or most of the elements listed above, or it can be retrofitted over an existing lock device 22.

To retrofit the intelligent door lock system 10 with an existing lock system, the user makes sure that the existing lock device 22 and bolt/lock 24 is installed right-side up. The existing thumb-turn is then removed. With some lock devices 22, additional mounting plates 26 need to be removed and the intelligent door lock system 10 can include replacement screws 56 that are used. The correct mounting plate 26 is then selected. With the existing screws 56 in the thumb-turn, the user sequentially aligns with 1 of 4 mounting plates 26 that are supplied or exist. This assists in determining the correct diameter and replace of the screws 56 required by the bolt/lock 24. The mounting plate 26 is then positioned. The correct adapter 28 is positioned in a center of the mounting plate 26 to assist in proper positioning. Caution is made to ensure that the adapter 28 does not rub the sides of the mounting plate 26 and the screws 56 are then tightened on the mounting plate 26. The intelligent door lock system bolt/lock 24 of lock device 22 is then attached. In one embodiment, this is achieved by pulling out side wing latches 36, sliding the lock device 22 and/or bolt/lock 24 over the adapter 28 and pin and then clamping down the wings 36 to the mounting plate 26. The faceplate is rotated to open the battery compartment and the battery tabs are then removed to allow use of the battery contacts 64. An outer metal ring 32 to lock and unlock the door 12 is then rotated. An app from mobile device 210 and/or key then brings the user through a pairing process.

A door 12 can be deformed, warped, and the like. It is desirable to provide a customer or user, information about the door, e.g., if it is deformed, out of alignment, if too much friction is applied when opening and closing, and the like.

As recited above, the current sensor 46 monitors the amount of current that goes to the motor 38 and this information is received and processed by the engine/processor 36 with memory and is coupled to the circuit 18. The amount of current going to the motor 38 is used to determine the amount of friction experienced by door 12 and/or lock device 22 in opening and/or closing, as applied by the intelligent door lock system 10 and the positioning sensing device 16 to the drive shaft 14. The circuit 18 and engine/processor 36 can provide for an adjustment of current. The engine/processor 36 can provide information regarding the door and friction to the user of the door 12.

In one embodiment of the present invention, the intelligent door lock system 10 provides an ability to sense friction on the lock device 22 and/or door 12 by measuring the torque required to move the bolt/lock 24. The intelligent door lock system 10 increases the applied torque gradually until the bolt/lock 24 moves into its desired position, and the applied torque is the minimum amount of torque required to move the bolt/lock 24, which is directly related to how deformed the door is.

In one embodiment, when a bad door is detected, a customer can be notified that their door may require some servicing. In one embodiment, door deformation can be detected with a torque device is used to determine if the torque applied when the door is rotated is too high. As a non-limiting example, this can be 2-15 in lbs of torque. The intelligent door lock system back end 68 can then perform a comparison between the measured torque with a standard, or a norm that is included in the one or more databases 88.

In one embodiment of the present invention, before the door is serviced, the intelligent door lock system 10 allows operation by offering a high-friction mode. As a non-limiting example, the high friction mode is when, as non-limiting examples, 2 inch lbs, 3 inch lbs., 3.5 inch pounds, and the like are required to open the door. In the high friction mode, the bolt/lock 24 is driven while the user is pushing, lifting, torqueing the door, pulling, performing visual inspections of rust, blockage, other conditions that can compromise a door and the like, that is applied to the doorknob. The position sensing device 16 is used to determine if the bolt/lock 24 was moved to a final position. In the high friction mode, motion of the door closing is confirmed. Upon detecting the closing of the door, the bolt/lock 24 is then driven. When the user receives an auditory, visual, or any other type of perceptible confirmation, the user then knows that the door has been locked. In one embodiment, the firmware elements, of the intelligent door lock system 10, as well as other door lock device 22 elements, can also attempt to drive the bolt/lock 24 for a second time when the first time fails. However, this can result in more power consumption, reducing lifetime of the power source, particularly when it is battery 50 based.

In one embodiment of the present invention, the intelligent door lock system 10 seeks to have the motor 38 operate with reduced energy consumption for energy source lifetime purposes, as well as eliminate or reduce undesirable noises, operations, and user experiences that occur when this is a failure in door locking and unlocking, particularly due to door deformation, door non-alignment, as well as other problems with the door that can be irritating to the person locking or unlocking the door.

In one embodiment of the present invention, the intelligent door lock system back-end 68 can track performance of doors and friction levels across time and build a service to encourage users to better maintain their doors. Such service can be a comparison of a door's friction level to other users that are similar geographic locations, at similar weather pattern, such that the user is encouraged to maintain their doors at a competent level. There can be a comparison to standards that at a certain level the door becomes unsafe. Guidelines are provided as to how to maintain their doors. This can be achieved by asking a door user what improves their door, including but not limited to, pushing, lifting, torqueing the door, pulling, visual inspections of rust, blockage, other conditions that can compromise a door, and the like. The analysis and comparison can be conducted at the back-end 68 and the results computed to door lock operator as well as others.

In one embodiment of the present invention, the intelligent door lock system 10 has a deformed operation mode that can be activated after a selected amount of time. As a non-limiting example, this can immediately after the user has been notified, more than 1 pico second, 1 second, 5 seconds, and greater periods of time. The deformed operation mode can be activated by the intelligent door lock system 10 itself, or by the intelligent door lock system back-end 68. It can be activated on the door operator's request. In one embodiment, the back-end 68 can anticipate these problems. As non-limiting examples, these can include but are not limited to, due to analysis of doors 12 in similar geographic areas, doors under similar conditions, doors with similar histories, similar environmental conditions, as well as the history of a particular door, and the like.

The deformed mode provides cooperation with the door user to more readily open the door. In one embodiment, this is a mechanism for the door to communicate back to the door lock operator. As a non-limiting example, feedback can be provided to the door operator. Such feedback can include, but is not limited to, communication via, tactile, audio, visual, temperature, electronic, wirelessly, through a computer, mobile device and the like. In another embodiment, the operator can signify to the door the operator's desire to leave by unlocking and opening the door 12. This is a door operator and lock communication. The door operator can close the door, which is sensed by the intelligent door lock system 10, a timer can then be initiated to provide with door operator with a selected time period in which the door operator can manually alleviate the friction problem. When the time has expired, the intelligent door system 10 can then lock the door 12. Upon detecting a successful door locking event, the intelligent door lock system 10 can advise the door operator that there is a successful door locking. If the door locking is not successful, the intelligent door lock system 10 can provide a message to the door operator via a variety of means, including but not limited to a message or alert to the door lock operator's mobile device. Such a mobile device message provides the door operator with notification that door locking was not successful or achieved, and the door lock operator can then take action to lock the door 12 either in person, wirelessly, and the like.

For entry, communication with the lock device 22 may be different. In one embodiment, it can be locking coupled with close proximity to a mobile device that is exterior to the door.

In another embodiment of the present invention, the intelligent door lock system back-end 68 can track performance of doors and friction levels across time and build a simple service to encourage users to maintain their doors better, as discussed above.

This information can be stored in the one or more databases 64.

In one embodiment of the present invention, the intelligent door lock system 10 unlocks when a selected temperature is reached, when smoke is detected, when a fire is detected by processor 38 and the like. As non-limiting examples, the intelligent door lock system 10 unlocks the bolt/lock 24 when a temperature is sensed by the temperature sensor 46 that, as non-limiting examples, is greater than 40 degrees C. any temperature over 45 degrees C. and the like. The temperature sensor 46 212 sends a signal to the processor 36 which communicates with the motor 38 that will then cause the drive shaft 14 to rotate sufficiently and unlock the bolt/lock 24. An arm can also be activated. It will be appreciated that the processor 36 can be anywhere as long as it is in communication with the temperature sensor 46, and the motor 38, which can be at the intelligent door lock system 10, at the back-end 68, anywhere in the building, and at any remote location. The processor 36 determines if there is an unsafe condition, e.g., based on a rise in temperature and this then results in an unlocking of the bolt/lock 24.

In one embodiment, the intelligent door lock system back-end 68 can track performance of doors and friction levels across time and build a service to encourage users to better maintain their doors, as discussed above.

FIG. 17 is a diagram illustrating an implementation of an intelligent door look system 100 that allows an intelligent lock on one or more buildings to the controlled, as described above, and also controlled remotely by a mobile device or computer, as well as remotely by an intelligent lock system back-end component 114, a mobile device or a computing device 210 of a user who is a member of the intelligent door lock system 100, as disclosed above. The intelligent door lock system back-end component 114 may be any of those listed above included in the intelligent lock system back-end 68, one or more computing resources, such as cloud lock access services computing resources or server computers with the typical components, that execute a plurality of lines of computer code to implement the intelligent door lock system 100 functions described above and below. Each computing device 210 of a user may be a processing unit based device with sufficient processing power, memory and connectivity to interact with the intelligent door lock system back-end component 114. As a non-limiting example, the mobile device or computing device 210 may be as defined above, and include those disclosed below, that is capable of interacting with the intelligent door lock back-end component 114. In one implementation, the mobile device or computing device 210 may execute an application stored in the memory of the mobile device computing device 210 using a processor from the mobile device or computing device 210 to interact with the intelligent door lock back-end component 114. Examples of a user interface for that application is shown in FIGS. 21 (a)-22(e) discussed below in more detail.

In another embodiment, the mobile device or computing device 210 may execute a browser stored in the memory of the mobile or computing device 210 using a processor from the mobile device or computing device 210 to interact with the intelligent door lock system back-end component 114. Each of the elements shown in FIG. 17 may be linked by System Networks, including but not limited to a cellular network, a Bluetooth system, the Internet (HTTPS), a WiFi network and the like.

As shown in FIG. 17, each user's mobile device or computer 210 may interact with the intelligent door lock system back-end 68 over System Networks, including but not limited to a wired or wireless network, such as a cellular network, digital data network, computer network and may also interact with the intelligent door lock system 10 using System Networks. Each mobile device or computing device 210 may also communicate with a WiFi network 115 or Network Systems over, as a non-limiting example, a network and the WiFi network 115 may then communicate with the intelligent door lock system 10.

FIGS. 18(a) and (b) illustrate a front view and a back view, respectively, of a door 120 with intelligent door lock system 10. The front portion of the door 120 (that is outside relative to a building or dwelling) shown in FIG. 17 looks like a typical door 120 with a bolt assembly 122 and a doorknob and lock assembly 124. The back portion of the door 120, that is inside of the dwelling when the door 120 is closed, illustrated in FIG. 18(b) has the same doorknob and lock assembly 124, but then has an intelligent door lock system 100 that is retrofitted onto the bolt assembly 124 as described below in more detail.

The intelligent door look assembly 100 may have an extension gear which extends through the baseplate of the smart door lock. The baseplate may have one or more oval mounting holes to accommodate various rose screw distances from 18 mm to 32 mm to accommodate various different doors. In one implementation, the intelligent door lock system 100 may have a circular shape and also a rotating bezel. The rotating bezel allows a user to rotate the smart door lock and thus manually lock or unlock the bolt as before. The extension gear extends through the baseplate and then interacts with the existing bolt elements and allows the smart door lock to lock/unlocks the bolt. The extension gear may have a modular adapter slot at its end which interfaces with an extension rod of the bolt assembly 124. These modular adapters, as shown in FIG. 23(b), may be used to match the existing extension rod of the bolt assembly 124. The smart door lock housing may further include an energy source, such as a battery, a motor assembly, such as a compact, high-torque, high-accuracy stepper motor, and a circuit board that has at least a processor, a first wireless connectivity circuit and a second wireless connectivity circuit, as described above. In one embodiment, the first wireless connectivity circuit may be a Bluetooth chip that allows the smart door lock to communicate using a Bluetooth protocol with a computing device of a user, such as a smartphone, tablet computer and the like. The second wireless connectivity circuit may be a WiFi chip that allows the smart door lock to communicate using a WiFi protocol with a back-end server system. The circuit board components may be intercoupled to each other and also coupled to the energy source and the motor for power and to control the motor, respectively. Each of the components described here may be coupled to the energy source and powered by the energy source.

FIG. 19 illustrates the smart door lock system 100 being retrofitted onto a bolt in a door 10. As shown in FIG. 19, when the intelligent door lock system 100 is installed on the door 120, the thumb turn 124 is removed (replaced by the bezel that allows the user to manually unlock or lock the bolt.) In addition, the extension gear 126 of the intelligent door lock system 100, and more specifically the slotted portion 126(a) at the end of the extension gear, is mechanically coupled to the extension rod 128 of the bolt assembly as show in FIG. 19. When the intelligent door lock system 100 is installed, as shown in FIG. 19, the user can rotate the bezel 132 to manually lock or unlock the bolt assembly. In addition, when commanded to do so, the motor assembly in the intelligent door lock system 100 can also turn the extension gear 126 that in turn turns the extension rod and lock or unlock the bolt assembly. Thus, the extension gear 126 allows the smart door lock to act as a manual thumb turn (using the bezel) and rotate either clockwise or counterclockwise to engage or disengage the bolt of a bolt. The extension gear 126 is designed in a manner to control the physical rotation of extension rods/axial actuators/tail pieces/tongues 128 which are traditional rotated by means of a thumb turn. This is achieved by designing the extension gear 126 with modular gear adapters as shown in FIG. 23(b) to fit over the extension rod 22 as shown. This allows the extension gear 126 to fit with a variety of existing extension rods.

FIG. 20 illustrates a set of interactions between the intelligent door lock system 100, mobile or computing device 210 and intelligent door lock system back-end 68, that may include a pairing process 138 and a lock operation process 140. During the pairing process 138, the intelligent door lock system 100 and mobile or computing device 210 can be paired to each other and also authenticated by the intelligent door lock system back-end 68. Thus, as shown in FIG. 20, during the pairing process, the intelligent door look system 100 is powered on and becomes discoverable, while the mobile or computing device 210 communicates with the intelligent door lock system back-end 68, and has its credentials validated and authenticated. Once the mobile or computing device 210, and the app on the mobile or computing device 210, is authenticated, the mobile or computing device 210 discovers the lock, such as through a Bluetooth discovery process, since the intelligent door look system 100 and the mobile or computing device 210 are within a predetermined proximity to each other. The mobile or computing device 210 may then send a pairing code to the intelligent door look system 100, and in turn receive a pairing confirmation from the intelligent door lock system 100. The pairing process is then completed with the processes illustrated in FIG. 20. The lock operation may include the steps listed in FIG. 20 to operate the intelligent door look system 100 wirelessly using the mobile or computing device 210.

The intelligent door lock system 100 may be used for various functions. As a non-limiting example, the intelligent door lock system 100 may enable a method to exchange a security token between mobile or computing device 210 and the intelligent door look system 100. All or all of the intelligent door look systems 100 may be registered with the intelligent door lock back-end 68 with a unique registration ID. The unique ID of the an intelligent door look system 100 may be associated with a unique security token that can only be used to command a specific intelligent door look system 100 to lock or unlock. Through a virtual key provisioning interface of the intelligent door lock system back-end 68, a master user, who may be an administrator, can issue a new security token to a particular mobile or computing device 210. The intelligent door look system 100 can periodically broadcast an advertisement of its available services over System Networks. When the mobile or computing device 210 is within a predetermined proximity of the intelligent door look system 100, which varies depending on the protocol being used, the mobile or computing device 210 can detect the advertisement from the intelligent door lock assembly 100.

The application on the mobile or computing device 210 detects the intelligent door look system 100 and a communications session can be initiated. The token, illustrated as a key 118 in FIG. 20, is exchanged and the lock is triggered to unlock automatically. Alternatively, if the intelligent door look system 100 is equipped with a second wireless communications circuit, then the intelligent door look system 100 can periodically query the intelligent door lock system back-end 68 for commands. A user can issue commands via a web interface to the intelligent door lock system back-end 68, and the intelligent door look system 100 can lock or unlock the door 120. The intelligent door lock system 100 may also allow the user to disable auto-unlock, at which time the application on the user's mobile or computing device 210 can provide a notification which then allows the user to press a button on the mobile or computing device 210 to lock or unlock the lock.

The intelligent door lock system 100 may also allow for the triggering of multiple events upon connection to an intelligent door look system 100 by a mobile or computing device 210. As a non-limiting example, the intelligent door look system 100 can detect and authenticate the mobile or computing device 210, as described herein, and initiate a series of actions, including but not limiting to, unlocking doors 100, turning on lights, adjusting temperature, turning on stereo etc. The commands for these actions may be carried out by the mobile or computing device 210 or the intelligent door lock system back-end 68. In addition, through a web interface of the intelligent door lock system back-end 68, the user may define one or more events to be triggered upon proximity detection and authentication of the user's mobile or computing device 210 to the intelligent door look system 100.

The intelligent door lock system 100 may also allow for the intelligent triggering of events associated with an individual. In particular, environmental settings may be defined per individual in the intelligent door lock system back-end 68 and then applied intelligently by successive ingress by that person into a building that has an intelligent door look system 100. For example: person A arrives home and its mobile or computing device 210 is authenticated by the intelligent door look system 100. His identity is shared with the intelligent door lock system back-end 68. The intelligent door lock system back-end 68 may send environmental changes to other home controllers, such as “adjust heat to 68 degrees”. Person B arrives at the same building an hour later and her mobile or computing device 210 is also authenticated and shared with the intelligent door lock system back-end 68. The intelligent door lock system back-end 68 accesses her preferred environmental variables such as “adjust heat to 71 degrees”. The intelligent door lock system back-end understands that person B has asked for a temperature increase and issues the respective command to the dwelling thermostat. In one example, the intelligent door lock back-end system 68 has logic that defers to the higher temperature request or can deny it. Therefore if person A entered the home after person B, the temperature would not be decreased.

FIGS. 21 (a)-(g) are examples of a user interface for an owner of a building that has an intelligent door lock system 100. These user interfaces may be seen by a user who is the owner of a building that has an intelligent door look system 1OO with the unique ID. FIG. 21 (a) is a basic home screen while FIG. 22(b) shows the smart door locks (in a keychain) which the user of the mobile or computing device 210 has access rights to in intelligent door lock system 100. FIG. 21 (c) illustrates an example of a user interface when a particular intelligent door look system 100 is locked. FIG. 22(d) illustrates an example of a user interface when a particular intelligent door look system 100 is unlocked. FIGS. 21 (e) and (f) are user interface examples that allow the owner to add other users/people to be able to control the intelligent door look system 100 of the building. FIG. 21 (g) is an example of a configuration interface that allows the owner of the building to customize a set of permissions assigned for each intelligent door lock system 100.

FIGS. 22(a)-(e) are examples of a user interface for a guest of an owner of a building that has an intelligent door lock system 100.

FIGS. 23(a) and (b) illustrate an intelligent door look system 100 and extension gear adapters 142. In particular, FIG. 23(a) shows the bolt of a lock device with an empty extension gear receptacle that allows different extension gear adapters 150 (shown in FIG. 7B) to be inserted into the receptacle so that the an intelligent door look system 100 may be used with a number of different bolts of lock devices that each have a different shaped extension rod and/or extension rods that have different cross-sections.

Referring now to FIG. 24, 1212 is a block diagram illustrating embodiments of a mobile or computing device 210 that can be used with intelligent door lock system 10.

The mobile or computing device 210 can include a display 1214 that can be a touch sensitive display. The touch-sensitive display 1214 is sometimes called a “touch screen” for convenience, and may also be known as or called a touch-sensitive display system.

The mobile or computing device 210 may include one or more optical sensors 1238. These components may communicate over one or more communication buses or signal lines 1240.

It should be appreciated that the mobile or computing device 210 is only one example of a portable multifunction mobile or computing device 210, and that the mobile or computing device 210 may have more or fewer components than shown, may combine two or more components, or a may have a different configuration or arrangement of the components. The various components shown in FIG. 24 may be implemented in hardware, software or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 1216 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 1216 by other components of the mobile or computing device 210, such as the CPU 1220 and the peripherals interface 1222, may be controlled by the memory controller 1218.

The peripherals interface 1222 couples the input and output peripherals of the device to the CPU 1220 and memory 1216. The one or more processors 1220 run or execute various software programs and/or sets of instructions stored in memory 1216 to perform various functions for the mobile or computing device 210 and to process data.

In some embodiments, the peripherals interface 1222, the CPU 1220, and the memory controller 1218 may be implemented on a single chip, such as a chip 1242. In some other embodiments, they may be implemented on separate chips.

The Network System circuitry 1244 receives and sends signals, including but not limited to RF, also called electromagnetic signals. The Network System circuitry 1244 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. The Network Systems circuitry 1244 may include well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. The Network Systems circuitry 1244 may communicate with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication.

The wireless communication may use any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA). BLUETOOTH®, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11 b, IEEE 802.11 g and/or IEEE 802.11 n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for email (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), and/or Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS)), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

The audio circuitry 1226, the speaker 1228, and the microphone 1230 provide an audio interface between a user and the mobile or computing device 210. The audio circuitry 1226 receives audio data from the peripherals interface 1222, converts the audio data to an electrical signal, and transmits the electrical signal to the speaker 1228. The speaker 1228 converts the electrical signal to human-audible sound waves. The audio circuitry 1226 also receives electrical signals converted by the microphone 1230 from sound waves. The audio circuitry 1226 converts the electrical signal to audio data and transmits the audio data to the peripherals interface 1222 for processing. Audio data may be retrieved from and/or transmitted to memory 1216 and/or the Network Systems circuitry 1244 by the peripherals interface 1222. In some embodiments, the audio circuitry 1226 also includes a headset jack. The headset jack provides an interface between the audio circuitry 1226 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

The I/O subsystem 1232 couples input/output peripherals on the mobile or computing device 210, such as the touch screen 1214 and other input/control devices 1234, to the peripherals interface 1222. The I/O subsystem 1232 may include a display controller 1246 and one or more input controllers 210 for other input or control devices. The one or more input controllers 1 receive/send electrical signals from/to other input or control devices 1234. The other input/control devices 1234 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, and joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 1252 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons may include an up/down button for volume control of the speaker 1228 and/or the microphone 1230. The one or more buttons may include a push button. A quick press of the push button may disengage a lock of the touch screen 1214 or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, which is hereby incorporated by reference in its entirety. A longer press of the push button may turn power to the mobile or computing device 210 on or off. The user may be able to customize a functionality of one or more of the buttons. The touch screen 1214 is used to implement virtual or soft buttons and one or more soft keyboards.

The touch-sensitive touch screen 1214 provides an input interface and an output interface between the device and a user. The display controller 1246 receives and/or sends electrical signals from/to the touch screen 1214. The touch screen 1214 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects, further details of which are described below.

A touch screen 1214 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch screen 1214 and the display controller 1246 (along with any associated modules and/or sets of instructions in memory 1216) detect contact (and any movement or breaking of the contact) on the touch screen 1214 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen 1214 and the user corresponds to a finger of the user.

The touch screen 1214 may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen 1214 and the display controller 1246 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with a touch screen 1214.

A touch-sensitive display in some embodiments of the touch screen 1214 may be analogous to the multi-touch sensitive tablets described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in their entirety. However, a touch screen 1214 displays visual output from the portable mobile or computing device 210, whereas touch sensitive tablets do not provide visual output.

A touch-sensitive display in some embodiments of the touch screen 1214 may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 12, 2006; (2) U.S. patent application Ser.

No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety.

The touch screen 1214 may have a resolution in excess of 1000 dpi. In an exemplary embodiment, the touch screen has a resolution of approximately 1060 dpi. The user may make contact with the touch screen 1214 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which are much less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, the mobile or computing device 210 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen 1214 or an extension of the touch-sensitive surface formed by the touch screen.

In some embodiments, the mobile or computing device 210 may include a physical or virtual click wheel as an input control device 1234. A user may navigate among and interact with one or more graphical objects (henceforth referred to as icons) displayed in the touch screen 1214 by rotating the click wheel or by moving a point of contact with the click wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the click wheel). The click wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the click wheel or an associated button. User commands and navigation commands provided by the user via the click wheel may be processed by an input controller 1252 as well as one or more of the modules and/or sets of instructions in memory 1216. For a virtual click wheel, the click wheel and click wheel controller may be part of the touch screen 1214 and the display controller 1246, respectively. For a virtual click wheel, the click wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual click wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen.

The mobile or computing device 210 also includes a power system 1214 for powering the various components. The power system 1214 may include a power management system, one or more power sources (e.g., battery 1254, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

The mobile or computing device 210 may also include one or more sensors 1238, including not limited to optical sensors 1238. An optical sensor can be coupled to an optical sensor controller 1248 in I/O subsystem 1232. The optical sensor 1238 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. The optical sensor 1238 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with an imaging module 1258 (also called a camera module); the optical sensor 1238 may capture still images or video. In some embodiments, an optical sensor is located on the back of the mobile or computing device 210, opposite the touch screen display 1214 on the front of the device, so that the touch screen display may be used as a viewfinder for either still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of the optical sensor 1238 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor 1238 may be used along with the touch screen display for both video conferencing and still and/or video image acquisition.

The mobile or computing device 210 may also include one or more proximity sensors 1250. In one embodiment, the proximity sensor 1250 is coupled to the peripherals interface 1222. Alternately, the proximity sensor 1250 may be coupled to an input controller in the 1/0 subsystem 1232. The proximity sensor 1250 may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device.” filed Sep. 30, 2005; Ser. No. 11/240,788. “Proximity Detector In Handheld Device,” filed Sep. 30, 2005; Ser. No. 13/096,386, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862. “Automated Response To And Sensing Of User Activity In Portable Devices,” filed Oct. 24, 2006; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals.” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables the touch screen 1214 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call). In some embodiments, the proximity sensor keeps the screen off when the device is in the user's pocket, purse, or other dark area to prevent unnecessary battery drainage when the device is a locked state.

In some embodiments, the software components stored in memory 1216 may include an operating system 1260, a communication module (or set of instructions) 1262, a contact/motion module (or set of instructions) 1264, a graphics module (or set of instructions) 1268, a text input module (or set of instructions) 1270, a Global Positioning System (GPS) module (or set of instructions) 1272, and applications (or set of instructions) 1272.

The operating system 1260 (e.g., Darwin. RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

The communication module 1262 facilitates communication with other devices over one or more external ports 1274 and also includes various software components for handling data received by the Network Systems circuitry 1244 and/or the external port 1274. The external port 1274 (e.g., Universal Serial Bus (USB). FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Computer, Inc.) devices.

The contact/motion module 106 may detect contact with the touch screen 1214 (in conjunction with the display controller 1246) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The contact/motion module 106 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred, determining if there is movement of the contact and tracking the movement across the touch screen 1214, and determining if the contact has been broken (i.e., if the contact has ceased). Determining movement of the point of contact may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, the contact/motion module 106 and the display controller 1246 also detects contact on a touchpad. In some embodiments, the contact/motion module 1284 and the controller 1286 detects contact on a click wheel.

Examples of other applications that may be stored in memory 1216 include other word processing applications. JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

In conjunction with touch screen 1214, display controller 1246, contact module 1276, graphics module 1278, and text input module 1280, a contacts module 1282 may be used to manage an address book or contact list, including: adding name(s) to the address book; deleting name(s) from the address book; associating telephone number(s), e-mail address(es), physical address(es) or other information with a name; associating an image with a name; categorizing and sorting names; providing telephone numbers or e-mail addresses to initiate and/or facilitate communications by telephone, video conference, e-mail, or IM; and so forth.

FIGS. 25(a)-(e) represents a logical diagram of a cloud lock access services Infrastructure that can be utilized with the present invention that is in communication with the bridge 11. Bluetooth devices 21 and/or the intelligent door lock system 10. As shown, the cloud lock access services encompasses web applications, mobile devices, personal computer and/or laptops and social networks, such as. Twitter®. (“Twitter®” is a trademark of Twitter Inc.). It will be appreciated that other social networks can be included in the cloud lock access services and Twitter® has been given as a specific example. Therefore, every component forms part of the cloud lock access services which comprises servers, applications and clients as defined above.

The cloud lock access services based system facilitates adjusting utilization and/or allocation of hardware resource(s) to remote clients. The system includes a third party service provider, that is provided by the methods used with the present invention, that can concurrently service requests from several clients without lottery participant perception of degraded computing performance as compared to conventional techniques where computational tasks can be performed upon a client or a server within a proprietary intranet. The third party service provider (e.g., “cloud lock access services”) supports a collection of hardware and/or software resources. The hardware and/or software resources can be maintained by an off-premises party, and the resources can be accessed and utilized by identified lottery participants over Network System. Resources provided by the third party service provider can be centrally located and/or distributed at various geographic locations. For example, the third party service provider can include any number of data center machines that provide resources. The data center machines can be utilized for storing/retrieving data, effectuating computational tasks, rendering graphical outputs, routing data, and so forth.

In one embodiment the cloud is used for the remote door 12 status operation, remote door operation for locking, unlocking and the like.

According to an illustration, the third party service provider can provide any number of resources such as data storage services, computational services, word processing services, electronic mail services, presentation services, spreadsheet services, gaming services, web syndication services (e.g., subscribing to a RSS feed), and any other services or applications that are conventionally associated with personal computers and/or local servers. Further, utilization of any number of third party service providers similar to the third party service provider is contemplated. According to an illustration, disparate third party service providers can be maintained by differing off-premise parties and a lottery participant can employ, concurrently, at different times, and the like, all or a subset of the third party service providers.

By leveraging resources supported by the third party service provider, limitations commonly encountered with respect to hardware associated with clients and servers within proprietary intranets can be mitigated. Off-premises parties, instead of lottery participants of clients or Network System administrators of servers within proprietary intranets, can maintain, troubleshoot, replace and update the hardware resources. Further, for example, lengthy downtimes can be mitigated by the third party service provider utilizing redundant resources; thus, if a subset of the resources are being updated or replaced, the remainder of the resources can be utilized to service requests from lottery participants. According to this example, the resources can be modular in nature, and thus, resources can be added, removed, tested, modified, etc. while the remainder of the resources can support servicing lottery participant requests. Moreover, hardware resources supported by the third party service provider can encounter fewer constraints with respect to storage, processing power, security, bandwidth, redundancy, graphical display rendering capabilities, etc. as compared to conventional hardware associated with clients and servers within proprietary intranets.

The system can include a client device, which can be the wearable device and/or the wearable device lottery participant's mobile device that employs resources of the third party service provider. Although one client device is depicted, it is to be appreciated that the system can include any number of client devices similar to the client device, and the plurality of client devices can concurrently utilize supported resources. By way of illustration, the client device can be a desktop device (e.g., personal computer), mobile device, and the like. Further, the client device can be an embedded system that can be physically limited, and hence, it can be beneficial to leverage resources of the third party service provider.

Resources can be shared amongst a plurality of client devices subscribing to the third party service provider. According to an illustration, one of the resources can be at least one central processing unit (CPU), where CPU cycles can be employed to effectuate computational tasks requested by the client device. Pursuant to this illustration, the client device can be allocated a subset of an overall total number of CPU cycles, while the remainder of the CPU cycles can be allocated to disparate client device(s). Additionally or alternatively, the subset of the overall total number of CPU cycles allocated to the client device can vary over time. Further, a number of CPU cycles can be purchased by the lottery participant of the client device. In accordance with another example, the resources can include data store(s) that can be employed by the client device to retain data. The lottery participant employing the client device can have access to a portion of the data store(s) supported by the third party service provider, while access can be denied to remaining portions of the data store(s) (e.g., the data store(s) can selectively mask memory based upon lottery participant/device identity, permissions, and the like). It is contemplated that any additional types of resources can likewise be shared.

The third party service provider can further include an interface component that can receive input(s) from the client device and/or enable transferring a response to such input(s) to the client device (as well as perform similar communications with any disparate client devices). According to an example, the input(s) can be request(s), data, executable program(s), etc. For instance, request(s) from the client device can relate to effectuating a computational task, storing/retrieving data, rendering a lottery participant interface, and the like via employing one or more resources. Further, the interface component can obtain and/or transmit data over a Network System connection. According to an illustration, executable code can be received and/or sent by the interface component over the Network System connection. Pursuant to another example, a lottery participant (e.g. employing the client device) can issue commands via the interface component.

In one embodiment, the third party service provider includes a dynamic allocation component that apportions resources, which as a non-limiting example can be hardware resources supported by the third party service provider to process and respond to the input(s) (e.g., request(s), data, executable program(s), and the like, obtained from the client device.

Although the interface component is depicted as being separate from the dynamic allocation component, it is contemplated that the dynamic allocation component can include the interface component or a portion thereof. The interface component can provide various adaptors, connectors, channels, communication paths, etc. to enable interaction with the dynamic allocation component.

In one embodiment a system includes the third party service provider that supports any number of resources (e.g., hardware, software, and firmware) that can be employed by the client device and/or disparate client device(s) not shown. The third party service provider further comprises the interface component that receives resource utilization requests, including but not limited to requests to effectuate operations utilizing resources supported by the third party service provider from the client device and the dynamic allocation component that partitions resources, including but not limited to, between lottery participants, devices, computational tasks, and the like. Moreover, the dynamic allocation component can further include a lottery participant state evaluator, an enhancement component and an auction component.

The user state evaluator can determine a state associated with a user and/or the client device employed by the user, where the state can relate to a set of properties. For instance, the user state evaluator can analyze explicit and/or implicit information obtained from the client device (e.g., via the interface component) and/or retrieved from memory associated with the third party service provider (e.g., preferences indicated in subscription data). State related data yielded by the user state evaluator can be utilized by the dynamic allocation component to tailor the apportionment of resources.

In one embodiment, the user state evaluator can consider characteristics of the client device, which can be used to apportion resources by the dynamic allocation component. For instance, the user state evaluator can identify that the client device is a mobile device with limited display area. Thus, the dynamic allocation component can employ this information to reduce resources utilized to render an image upon the client device since the cellular telephone may be unable to display a rich graphical user interface.

Moreover, the enhancement component can facilitate increasing an allocation of resources for a particular lottery participant and/or client device.

In one embodiment a system employs load balancing to optimize utilization of resources. The system includes the third party service provider that communicates with the client device (and/or any disparate client device(s) and/or disparate third party service provider(s)). The third party service provider can include the interface component that transmits and/or receives data from the client device and the dynamic allocation component that allots resources. The dynamic allocation component can further comprise a load balancing component that optimizes utilization of resources.

In one embodiment, the load balancing component can monitor resources of the third party service provider to detect failures. If a subset of the resources fails, the load balancing component can continue to optimize the remaining resources. Thus, if a portion of the total number of processors fails, the load balancing component can enable redistributing cycles associated with the non-failing processors.

In one embodiment a system archives and/or analyzes data utilizing the third party service provider. The third party service provider can include the interface component that enables communicating with the client device. Further, the third party service provider comprises the dynamic allocation component that can apportion data retention resources, for example. Moreover, the third party service provider can include an archive component and any number of data store(s). Access to and/or utilization of the archive component and/or the data store(s) by the client device (and/or any disparate client device(s)) can be controlled by the dynamic allocation component. The data store(s) can be centrally located and/or positioned at differing geographic locations. Further, the archive component can include a management component, a versioning component, a security component, a permission component, an aggregation component, and/or a restoration component.

The data store(s) can be, for example, either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory. By way of illustration, and not limitation, nonvolatile memory can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), or flash memory. Volatile memory can include random access memory (RAM), which acts as external cache memory. By way of illustration and not limitation. RAM is available in many forms such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DOR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM). Rambus direct RAM (RDRAM), direct Rambus dynamic RAM (DRDRAM), and Rambus dynamic RAM (RDRAM). The data store(s) of the subject systems and methods is intended to comprise, without being limited to, these and any other suitable types of memory. In addition, it is to be appreciated that the data store(s) can be a server, a database, a hard drive, and the like.

The management component facilitates administering data retained in the data store(s). The management component can enable providing multi-tiered storage within the data store(s), for example. According to this example, unused data can be aged-out to slower disks and important data used more frequently can be moved to faster disks; however, the claimed subject matter is not so limited. Further, the management component can be utilized (e.g. by the client device) to organize, annotate, and otherwise reference content without making it local to the client device. Pursuant to an illustration, enormous video files can be tagged via utilizing a cell phone. Moreover, the management component enables the client device to bind metadata, which can be local to the client device, to file streams (e.g., retained in the data store(s)); the management component can enforce and maintain these bindings.

Additionally or alternatively, the management component can allow for sharing data retained in the data store(s) with disparate lottery participants and/or client devices. For example, fine-grained sharing can be supported by the management component.

The versioning component can enable retaining and/or tracking versions of data. For instance, the versioning component can identify a latest version of a document (regardless of a saved location within data store(s)).

The security component limits availability of resources based on lottery participant identity and/or authorization level. For instance, the security component can encrypt data transferred to the client device and/or decrypt data obtained from the client device. Moreover, the security component can certify and/or authenticate data retained by the archive component.

The permission component can enable a lottery participant to assign arbitrary access permissions to various lottery participants, groups of lottery participants and/or all lottery participants.

Further, the aggregation component assembles and/or analyzes collections of data. The aggregation component can seamlessly incorporate third party data into a particular lottery participant's data.

The restoration component rolls back data retained by the archive component. For example, the restoration component can continuously record an environment associated with the third party service provider. Further, the restoration component can playback the recording.

Algorithm

FIG. 27 is a flowchart illustrating an example of a process for tracking signal strength of between the bridge 11 and the Bluetooth LE devices 21, as well as the intelligent door lock system 10. While FIG. 27 illustrates exemplary steps according to one embodiment, other embodiments may omit, add to, and/or modify any of the steps shown in FIG. 27.

An algorithm described hereafter computes proximity of a Bluetooth device 21 from the intelligent door lock system 10 of a dwelling and from the one or more bridges in the dwelling. The relative signal strength of connections to these two devices during lock operations is recorded as a threshold value. When the proximity to the bridge, placed inside the home is closer than before the lock operation, we will compute algorithmically that the device is inside the home.

In one embodiment the time spent with a relatively consistent signal strength value is a strong indicator a person being in the dwelling. A rapid change of proximity following a lock operation will be an indicator of coming.

In one embodiment a lock device 22 operation of the intelligent door lock system 10 followed by a rapid change of proximity is an indicator of going from the dwelling.

A process begins by measuring the signal strength of wireless signals between the bridge 11 and the Bluetooth LE devices 21. The signal strength may be measured in any of the ways discussed above, including the bridge 11 measuring the power of downstream wireless signals. This step may be initiated in accordance with a predefined schedule or in response to a predetermined event.

Parameter data of the non-interconnect device is next determined. The parameter data may include location, time, and/or velocity coordinates associated with the non-interconnect device at the time of the signal strength measurement. This step may be performed in any variety of ways, including but not limited to the use of GPS information. Further, this step may be initiated by a predefined schedule or a predefined event, as discussed above.

Next, the signal strength and parameter data are transmitted to the cloud lock access services. This step may be performed in any of the ways discussed above, including using upstream control, communication, or out-of-band channels of Network System. The signal strength and parameter data, and optionally additional data, may be combined to form network status data, which is transmitted to the cloud lock access services.

Next, the signal strength and parameter data are used to analyze the signal strength between the bridge 11 and a Bluetooth LE device 21. The network operations center 150 is able to process the data in any of the ways discussed above, including mapping the signal strength to geographic representations of the bridge 11 and a Bluetooth LE device 21, based on the parameter data. A graphical representation of at least a section of the strength of the signal between the bridge 11 and a Bluetooth LE device 12 may be generated to illustrate instances of measured signal strength plotted based on corresponding parameter data. Network operators may use the output of the cloud lock access services to analyze, configure, reconfigure, overhaul, and/or optimize the wireless network, as discussed above.

FIG. 26 is a flowchart illustrating another example of a process for tracking signal strength between the bridge 11 and a Bluetooth LE device 21. While FIG. 26 illustrates exemplary steps according to one embodiment, other embodiments may omit, add to, and/or modify any of the steps shown in FIG. 26.

The process of FIG. 26 begins by measuring the signal strength between the bridge 11 and a Bluetooth LE device 21 at step 410. The signal strength may be measured in any of the ways discussed above, including measuring the power of downstream wireless signals being received from the cloud lock access services relative to bridge 11 and a Bluetooth LE device 21. Step 410 may be initiated in accordance with a predefined schedule or in response to a predetermined event.

At step 420, it is determined whether the measured signal strength is lower than a predetermined threshold. The predetermined threshold may be defined by network operators and may be based on a desired level of signal power that provides effective signal strength. If it is determined at step 420 that the measured signal strength is not lower than the predetermined threshold, the process returns to step 410, at which step another measurement of signal strength is obtained either immediately, according to an established schedule, or in response to a predetermined trigger event.

On the other hand, if it is determined at step 420 that the measured signal strength is lower than the predetermined threshold, the process continues at step 430. In one embodiment, at step 430, parameter data of the Bluetooth LE device 21 is determined. As non-limiting examples, the parameter data may include location, time, and/or velocity coordinates associated with the Bluetooth LE device 21 relative to the bridge 11. Step 430 may be performed in any of the ways discussed above, including using GPS signals to determine GPS coordinate data.

At step 440, it is determined whether the measured signal strength is adequate for transmission of data upstream to the cloud lock access services from the Bluetooth LE device 21. Step 440 may be performed by comparing the measured signal strength to a predetermined transmission threshold, which may be defined by network operators based on a level of signal power that supports reliable upstream data transmissions from the wireless device.

If it is determined at step 440 that the measured signal strength is inadequate for transmission of data, the process continues at step 445. At step 445, the signal strength and parameter data are buffered for subsequent transmission. Step 445 may be performed by storing the data to memory to maintain the data until it can be transmitted. In one embodiment, from step 445, the process returns to step 410 to obtain another measurement of signal strength. Multiple instances of data may be buffered until signal strength becomes strong enough for the stored data to be transmitted from the Bluetooth LE device 21. In other words, steps 410-440 may be repeated with different measurements being gathered and stored for later transmission when the signal strength becomes strong enough to support upstream transmissions.

If it is determined at step 440 that the measured signal strength is adequate for data transmission, the process continues to step 450. At step 450, the signal strength and parameter data are transmitted to the cloud lock access services. Step 450 may be performed in any of the ways discussed above, including using upstream control, communication, or out-of-band channels of the wireless network 144. The signal strength and parameter data, and optionally additional data, may be combined to form network status data, which is transmitted to the cloud lock access services at step 450.

At step 460, the signal strength and parameter data are used to analyze any number of parameters relative to Bluetooth LE device 21, particularly its location. The cloud is able to process the data in any of the ways discussed above, including mapping the signal strength to geographic representations of the wireless network 144, based on the parameter data. A graphical representation may be generated to illustrate instances of measured signal strength plotted based on corresponding parameter data.

In one embodiment a triangulation algorithm for location estimation can be used for the bridge 11, the intelligent door lock system 10 and a Bluetooth LE device 21. In one embodiment the triangulation computes the location estimate by solving systems of quadratic equations. In one embodiment the triangulation forms circles whose centers are the locations of the transmitters, e.g., access points or base stations. Geometries other than circles can be used. In FIG. 27, the locations and RF characteristics of access points 1, 2, and 3 of the bridge 11, the intelligent door lock system 10 and the Bluetooth LE device 21 have been obtained at numerous known locations. Distances d1 between the object and the access point 1, d2 between the bridge 11, the intelligent door lock system 10 and the Bluetooth LE device 21 and the access point 2, and d3 between them and the access point 3 are calculated based on radio wave characteristics, e.g., TOA or TDOA. It will be appreciated than communication other than radio waves can be used.

Triangulation forms sets of circles. Each of the reference points, access points 1, 2 or 3, becomes the center of a circle, and the distances between the object and the center, d1, d2 or d3, becomes the radius of that circle.

Triangulation estimates locations based on various intersection areas formed by these circles. If three formed circles meet at a single spot, that spot becomes the location estimate as a result of the triangulation. However, as a practical matter, the three circles rarely will meet at a single spot. More often, if the circles intersect, they will intersect in multiple spots. In FIG. 27, the three circles have six intersection points, P1, P2, P3. P4, P5 and P6. The triangulation algorithm examines areas formed by the intersection points to obtain a location estimate for the bridge 11, the intelligent door lock system 10 and the Bluetooth LE device. Specifically, the triangle formed by P2, P4 and P5 has the smallest area among all possible triangles formed by these intersection points, and the centroid X of the triangle (P2, P4, P5) is the best location estimate of the object.

In one embodiment, as shown in FIG. 28, a K-nearest neighbor averaging algorithm for location estimate is used, wherein K=5. Typically. K is larger than 2. Experimental analysis shows that K=3 gives the best performance. Let a triplet (Sa, Sb, Sc) represent a set of run-time signal strength measurements at a location of interest from the bridge 11, the intelligent door lock system 10 and the Bluetooth LE device 21, represented as a, b, and c. Five triplets which have the least root mean square (RMS) error in signal strength between the run-time and the off-line measurements are found. The root mean square error in signal strength is calculated as follows:

rms=√{square root over((a−ai)2+(b−bi)2+(c−ci)2)}{square root over((a−ai)2+(b−bi)2+(c−ci)2)}{square root over((a−ai)2+(b−bi)2+(c−ci)2)}  (1)

wherein (Sa, Sb, Sc) represents off-line signal strength measurements at the location of interest.

In particular, these five triplets are: signal strength triplet (a1, b1, c1) at position L1 (x1, y1) from a, b and c; signal strength triplet (a2, b2, c2) at position L2 (x2, y2) from a, b and c; and signal strength triplet (a5, b5, c5) at position L5 (x5, y5) from a, b and c. L1, . . . , L5 are determined by using the location information database. The location information database for RF-based static scene analysis typically contains entries used to map RF signal metrics to positions (i.e., transfer from signal domain to space domain). The positions of these five locations are averaged to yield the location estimate of the object as follows:

L=(L1+L2+L3+L4+L5)/5  (2)

In one embodiment, the smallest M-polygon algorithm for location estimate, wherein M=3. M is the number of access points, or base stations, used for the system. M=3 gives reasonably good performance for the algorithm. The bridge 11, intelligent door lock system 10 and Bluetooth LE device 21, represented as A, B. and C in FIG. 29, provide separate candidate locations A1, A2, B1, B2, C1 and C2 that match best with the off-line measurements. The algorithm then searches for the polygon that has the smallest perimeter formed by candidate locations contributed by each reference base station, wherein one and only one candidate from each base station must constitute a vertex of the polygon. In FIG. 29, candidate locations A1, B2 and C2 form the smallest perimeter polygon, in this case, a triangle. The final location estimate of the object is the centroid X of the polygon:

X=(A1+B2+C2)/3  (3)

In one embodiment the conventional static scene analysis maps from the radio signal domain to the space domain. The final estimate is typically within a coordinate system. A main drawback of the static scene analysis is that it cannot effectively cope with the impact of errors in the radio signal domain. Due to interference and noise, objects at different locations might be represented similarly in the radio signal domain, a phenomenon called aliasing. The conventional methods cannot detect aliasing, and may provide these different locations with similar location estimates.

In one embodiment a selective fusion location estimation (SELFLOC) algorithm selectively combines or fuses multiple location information sources to yield a combined estimate in a theoretically optimal manner. The SELFLOC algorithm is disclosed in U.S. patent application Ser. No. 10/330,523, filed Dec. 27, 2002, which is incorporated herein by reference.

In one embodiment, an overview of the SELFLOC algorithm to fuse three information sources 1, 2 and 3. Each input branch is individually weighted by one of the weights 1, 2, and 3. The sum of the weighted input branches provides the SELFLOC estimate.

The branch weights 1, 2 and 3 are calibrated during the off-line stage using error feedback. A minimum mean square error (MMSE) algorithm can be used for SELFLOC weight training and calibration. As shown in FIG. 4, three location estimates available independently are to be fused, and x-coordinates of these estimates are X1, X2 and X3. The weights for these input branches are w1, w2, and W3 respectively. Thus, the SELFLOC estimate X could be written as:

X=w1·X1+w2·X2+w3·X3.

Facial/Body Motion Detection

% In one embodiment a facial and/or body motion expression detector is used to detect the intent of a person. In one embodiment a digital still image is acquired that includes a face and/or body motion. A group of pixels is identified that corresponds to the face/body motion in the digital still image. A collection of low resolution images is generated in-camera, captured or otherwise obtained in-camera including multiple instances of the face/body motion. The face/body motion is tracked within the collection of low resolution images. In one embodiment cropped versions are acquired of images of the collection including the face/body motion. Facial/body motion expression state information of the face/body motion is accumulated based on the cropped versions. A statistical facial expression state of the face/body motion is classified. One or more facial/body motion expression state-dependent operations is/are initiated.

Embodiments of the invention employ in-camera training of new classifiers (i.e., instead of reusing the exact detection classifiers), that are used for separating one face/body motion from another. In certain embodiments, a binary classifier is built for face/body motions that are and/or should be recognized. This training means that upon user request samples of the target face/body motion are acquired by employing a face/body motion detection algorithm. These samples are then used as positive samples for a binary classifier. Negative samples are either used from a small collection of generic face/body motions and/or from other previously trained face/body motions, which are stored locally. A relatively short classifier cascade is then trained.

In certain embodiments, the process may be repeated for face/body motions that the user selects for future recognition. In a typical live view mode, the camera will run the tracking algorithm. A new detected face/body motion will be compared against the classifiers in the relatively short cascade in the recognition database. Depending on classifier responses and confidence accumulation, over several frames, a voting algorithm will choose one of the database face/body motions or decide that the face/body motion does not belong to the recognition set.

In certain embodiments, information from the detection process is used to adjust the recognition process. For one such embodiment, the adjustment of the recognition process is effected dynamically based on the detector/tracker.

In accordance with various embodiments a particular face/body motion may have a number of recognition profiles, since the illumination conditions can change the classifier responses quite significantly. When a previously trained face/body motion is not correctly recognized under a certain condition, a new recognition profile can be added to that face/body motion either automatically or upon user input.

In general, certain embodiments allow the use of detection classifiers to perform recognition based on detection probability. That is, the face/body motion detector probability output is used to re-scale the classifiers for the recognizer. For one such embodiment, the detector indicates if a face/body motion is a “strong” or “weak” face/body motion and then the result is boosted or suppressed in accordance with the indication.

For certain embodiments, facial/body motion expression detection works as an add-on feature to the face/body motion tracking algorithm. It will receive as input the face/body motion region in the form of a polygon such as a rectangle, or alternatively a square, rhombus, triangle, circle, or otherwise, as well as the already computed integral images and other available maps.

The facial/body motion expression detection algorithm will run a binary classifier on each of the tracked face/body motion regions and will decide with a certain degree of confidence whether each of the face/body motions is smiling or not smiling. If the required confidence level to provide an answer is not reached, the smiling-state of the face/body motion will be declared as uncertain or unknown. In certain embodiments, the prerequisites for the face/body motion may be that it should be frontal, with in-plane orientation close to 0, 90 or −90.

The facial/body motion expression classifier is the same type of chain with Haar and census features as the face/body motion detector. During the training part, it is learned to differentiate between positive smiling samples and negative non-smiling samples. The samples are face/body motion crops which are obtained by running the face/body motion detector and by automatic cropping based on manual or automatic markings on images with face/body motions. The samples may have the same upright orientation, with slight variations.

In an alternative embodiment of the system the samples could be mouth region crops, which hold most of the useful information for facial/body motion expression classification. Such alternative system involves an additional identification of the mouth region prior to the actual classification. This can be done by running a feature based mouth detector, or identifying the mouth by a maximum color saturation region in the bottom half of the face/body motion or another alternative method. This general approach adds an extra level of uncertainty, but may be advantageous in utilizing less data.

The training process may provide a binary classifier chain that can decide the smiling state for a whole face/body motion region as it is delivered by the face/body motion detector. Facial/body motion expression detection/classification may be executed on individual frames, but the logic spans over several frames as confidence is being accumulated in order to provide a consistent response for a certain face/body motion. On a particular frame, the facial/body motion expression classifier runs only on face/body motion rectangles (or other polygons) coming directly from the detector, because these are best centered and fitted over the face/body motion, before the tracking algorithm re-evaluates the rectangle position. The facial/body motion expression classifier is also evaluated at several slightly shifted positions around the face/body motion region.

A confidence based on these neighboring classifications is summed up and thresholded. A smiling decision can be positive, negative or inconclusive. The classifier evaluation is done by the same engine as the one running the face/body motion detector, but the facial/body motion expression classifiers are provided instead of the face/body motion ones. During a sequence of frames, a smiling confidence parameter assigned to each tracked face/body motion, is either incremented or decremented for each positive or, respectively, negative facial/body motion expression response. This confidence parameter may be integer, and may be bound by upper and lower limits such that the smiling decision is responsive enough, and will not lock in a certain state. The confidence parameter is updated after each facial/body motion expression classification (which occurs each frame or at an interval). The final facial/body motion expression state output for a face/body motion may be inquired at each frame (may be continuously output), and may be based on the sign and the absolute value of the integer confidence parameter.

In accordance with certain embodiments, an algorithm is capable of detecting smiling frontal face/body motions, as in-camera applications. The algorithm could be viewed as a standalone feature of digital cameras for facial/body motion expression detection (e.g., facial/body motion expression or frown detection). Certain embodiments may also be employed in apparatuses or methods involving decisions or further actions based on the presence of a smiling person and may include this algorithm as a decision algorithm.

In an alternative embodiment. Discreet Cosine Transforms (DCTs) are used.

In certain embodiments, the facial/body motion expression to be detected is a facial/body motion expression. There may be two databases, one with facial/body motion expressions, and the other with non-facial/body motion expression, greyscale images. A training algorithm is applied to each database. For one embodiment, the steps of the training algorithm may be identical or substantially the same for both databases. Crops may be used including entire face/body motions or just mouth regions or another subset at least including mouth regions, as outputted from a face/body motion detector. In alternative embodiments where blinks are being detected, then just eye region crops may be used or another subset at least including one or both eyes.

Images are read from the database (e.g., as squared crops delivered by the face/body motion detection algorithm). Then, for each image, the following steps may be performed:

1. Re-dimension the image to 25×25 pixels. This can be effected using bilinear interpolation, or alternatively bicubic splines.

2. Apply the 2DCT transform:

3. Set the pixels in the upper left corner of the transformed matrix (20% of the number of pixels on Ox times 20% of the number of pixels on Oy) to 0.

This corresponds to removing the low frequency coefficients which are related to person features

4. Apply the 21 DCT transform:

5. Set all the negative values to 0.

6. Apply an improved histogram equalization:

a. For each pixel, compute the mean of its horizontal, vertical and diagonal neighbours;

b. Sort pixels after their grey level, then after the computed mean;

c. Assign new levels of grey to each pixel;

d. Re-sort pixels in the original position.

The process will also work with conventional histogram equalization, though the quality of the results may be reduced.

7. Reshape the image to a vector (e.g. using vectorization).

For the whole database, after all images have been reshaped to vectors, perform the following steps:

8. Sort the vectors in 8 clusters using k-means. This is an arbitrary clustering that has been determined empirically to be sufficient to effect an advantageous concept. In general, the clustering may be different as will be appreciated by those skilled in the art.

9. Retain the cluster's centroids.

The training algorithm may be performed offline (i.e., the cluster centroids can be computed a priori and stored in a memory unit).

The following sequence may be applied for performing detection of facial/body motion expression or non-facial/body motion expressions (or blinks, etc.).

1. Load the cluster centroids.

2. Read the image to be classified.

3. If necessary, turn it to a grayscale image.

4. Re-dimension the image to 25×25 pixels.

5. Apply the 2DCT transform.

6. Set the pixels in the upper left corner of the transformed matrix (20% of the number of pixels on Ox times 20% of the number of pixels on Oy) to 0.

7. Apply the 21 DCT transform.

8. Set the negative values to 0.

9. Apply the improved histogram equalization.

10. Reshape the image to a vector.

11. Compute the Euclidian distances between the vector and all the clusters centroids.

Find the minimum distance.

Assign to the test image the same label (Facial/body motion expression or NonFacial/body motion expression) as the images within the closest cluster.

For certain embodiments, the number of clusters (e.g., 8 clusters for each database) may be varied. Additionally. or alternatively, the number of pixels made 0 after 2DCT (in this case 5×5 pixels) may be varied.

As will be appreciated by those skilled in the art, many alternative embodiments of the invention are possible. For example, the principle embodiment describes a technique that determines the facial/body motion expression/no-facial/body motion expression state of a face/body motion region within a digital image. It is implicit that a face/body motion tracking/face/body motion detector has been run on the image and that knowledge of the location of face/body motion region(s) within the analysed image is made available to the “facial/body motion expression detector”. This technique can be applied both within a digital camera given sufficient computing resources, and may be implemented partly within the camera (e.g. face/body motion detection) and partly outside the camera (e.g. facial/body motion expression detection using derived and saved face/body motion detection information), or in certain embodiments both the face/body motion detection process and the facial/body motion expression detection are used to post-process previously acquired images.

In one embodiment the digital camera may acquire a constant stream of preview and/or post-view images, and where a face/body motion tracking algorithm is embodied within the camera, then information about the determined face/body motion regions within each frame of the preview stream is available on a real-time basis. Where the present algorithm is sufficiently optimized, it can be applied in real-time either in parallel with, or sequentially following the application of the face/body motion tracker algorithm. Such an embodiment enables (i) improvements in the facial/body motion expression detection process itself and (ii) additional operational features to be provided to a user of the camera.

With respect to item (i) and referring to the computing of Euclidian distances between the vector and cluster centroids, and to the finding of minimum distance per steps 11 & 12 of the above-described exemplary embodiment, where such a real-time facial/body motion expression detection algorithm is implemented, it is possible to compute the facial/body motion expression/no-facial/body motion expression state of a tracked face/body motion region and to accumulate this state information over multiple pre-acquisition frames. This enables statistical analysis of the facial/body motion expression/no-facial/body motion expression state of a face/body motion and is useful to avoid confounding factors such as sudden changes in illumination and/or face/body motion pose which may degrade the accuracy of the facial/body motion expression detection algorithm. Thus, sudden inter-frame fluctuations in the facial/body motion expression feature vector can be ignored until the feature vector stabilizes.

In one embodiment in addition to calculating the facial/body motion expression feature vector for each frame, and determining its facial/body motion expression/no-facial/body motion expression state, the algorithm calculates a difference vector between subsequent frames of the preview/postview image stream. Where this is greater than a certain threshold it may either be interpreted as indicating a sudden change in external illumination or pose (which may be confirmed by the exposure determining subsystem of the camera for the case of illumination, or by the face/body motion-lock characterization of the face/body motion tracking algorithm) or it may be interpreted as a transition between facial/body motion expression and no-facial/body motion expression states (which may be confirmed by analysis of subsequent preview/postview frames).

In alternative embodiments, a running average of the facial/body motion expression feature vector may be calculated and this averaged feature vector is used to determine the facial/body motion expression/no-facial/body motion expression state of a face/body motion region over multiple preview frames.

In yet a further embodiment, the distances between the current facial/body motion expression feature vector and both the nearest facial/body motion expression centroid and the nearest no-facial/body motion expression centroid are calculated for each preview frame. The ratio between these two distances is analyzed statistically over several frames and used to determine a facial/body motion expression/no-facial/body motion expression probability measure rather than a simple facial/body motion expression/no-facial/body motion expression state measure. Thus where a facial/body motion expression feature vector is a normalized distance of 0.2 from the nearest facial/body motion expression centroid and a distance of 0.8 from the nearest no-facial/body motion expression centroid it is 80% likely to be a facial/body motion expression or 20% likely to be not a facial/body motion expression. In a variation on this embodiment the log of the normalized distance is used to calculate a probability rather than the normalized distance itself.

With respect to item (ii) above, where the facial/body motion expression detection process is operable on a preview/post-view stream, it is possible to monitor state transitions of tracked face/body motion regions. This enables, for example, a camera to implement an improved “group shot” feature, where an image is captured when everyone in a preview frame is determined to be smiling.

In other embodiments, the camera could issue a warning beep if one or more people are not smiling (the “facial/body motion expression guarantee” feature); or acquisition could delayed until everyone (or a plurality or certain percentage or certain number) are determined to be smiling.

In embodiments where additional image reconstruction and/or compositing and/or super-resolution algorithms are available within the camera then face/body motion regions, or portions thereof, from one or more preview frames may be combined with the main acquired image to ensure that a final, composited image presents the “best facial/body motion expression” for each detected face/body motion. The judging of the quality of a facial/body motion expression may be achieved using a facial/body motion expression/no-facial/body motion expression probability as described above.

Metadata relating to the facial/body motion expression/no-facial/body motion expression state or facial/body motion expression probability may be stored/saved with other information relating to the relevant tracked face/body motion region.
